After an investigation of the men’s basketball program spanning more than a year, the NCAA has delivered its Notice of Allegations to the University of Louisville and has charged the men’s basketball program with four Level One violations.

Those are the most serious violations in the association’s enforcement structure. They stem from revelations about strippers and escorts who were paid by former basketball staffer Andre McGee to provide entertainment for recruits and players – much of it in the on-campus basketball dorm named for coach Rick Pitino’s late brother-in-law, Billy Minardi. The investigation was spawned by the October 2015 tell-all book, “Breaking Cardinal Rules: Basketball and the Escort Queen,” written by Louisville madam Katina Powell.

In the Notice of Allegations that was made public by Louisville on Thursday, the NCAA alleges that McGee “arranged for and/or provided impermissible inducements, offers and/or extra benefits in the form of adult entertainment, sex acts and/or cash” to at least 17 recruits or current players, two AAU coaches and one friend of a recruit. The NCAA says the value of the impermissible benefits, which occurred between December 2010 and April 2014, was “at least $5,400.” The names of the involved recruits, players and AAU coaches in the report have been redacted by Louisville.
